I gotta admit I'm on Team I-Don't-Know-Why-I-Have-More-Than-One-Uke. I suppose it's some deep seated hoarding-like personality trait. I have many guitars, cameras, computers and gadgets of all kinds. Could try to rationalize, but at the end of the day, I get a charge out of the hunt and acquisition. I'm such a fan of the music and more so the artistic aspects of the physical instrument. The aesthetic and probably more important, the musical craftsmanship of the luthiers on this board is something I admire greatly. To be able to not only create a great looking piece but a great sounding and playable piece of art just blows me away. Add to it the fact that so many nice ukes are "relatively" accessible. Certainly more so than nice guitars.
I literally can feel my pulse quicken when a uke I've coveted hits the marketplace. I've even done the ol' "but I bought it as a gift to you" thing. My wife just rolls her eyes. She's got shoes and handbags (not a stereotype in our case), I've got my ukes etc. I have slowed acquisition down as I think I'm more in tune with what I like, but it took some of the previous buys to figure it out.
OK, so let's try to put a virtuous intent to it... I'm doing my best to single-handedly support the uke economy.
Or it's a cry for help.
